January 28, 1914
Gebhard Lebrecht, Prince Blücher von Wahlstatt, "a well-known German nobleman and a descendant of the Prussian hero of Waterloo," recently became the brother-in-law of his own son, reports the New York Times.
In January 1913, Count Lothar Blücher von Wahlstatt, married Princess Ludowika Radziwill, who is the elder sister of his stepmother, Princess Wanda Radziwill, whom his father married in 1895 at St. Petersburg.
Count Lothar is the Prince's son by his second marriage.
It is a very complicated relationship. Not only is Count Lothar his father's brother-in-law, "he is also the uncle of his younger siblings, and as the husband of his aunt, he becomes his own uncle."
If Count Lothar and his wife have a child, he will become "the latter's great-uncle and also his cousin."
Prince Blücher, who was born in 1836, has been married three times. He has five children, Countess Marie Ferdinandine, Countess Karoline,Count Gebhard, Count Gustav and Count Ferdinand, by his first wife, Princess Marie von Lobkowicz, who died in 1870. His second wife was Countess Elisabeth von Perponcher-Sedlnitzky, whom he married in 1889. They had two children: Count Lothar and Countess Gebhardine.
Elisabeth died in March 1894. A year later, Prince Blücher married Princess Wanda Radziwill, who was born in 1877. They have three young children, Countess Elisabeth, Countess Wanda and Count Hubert.
